REGISTER.

SPECIFICATION forming part of Letters Patent No. 504,239, dated August29, 1893.

Application filed March 18, 1893.

To @ZZ whom it may concern:

Be it known that I,v WILLIAM E. PATcHIN, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Registers; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, and tothe reference-numerals marked thereon.

My present invention has for its objects to provlde a register adaptedfor use in hot or cold air flues and located either in a wall or flooras may be desired, though especially desirable in the last mentionedposition because of its cleanliness, and it further has for its obt)ectsto provide one that is simple and cheap 1n construction and not liableto get out of order and to these and other ends it consists in certainnovelties in construction and combinations of parts, all as will behereinafter fully described, and the novel features pointed out In theclaims at the end of this specification.

In the drawings: Figure lis abottom plan view of my improved registeropen; Fig. 2, a longitudinal sectional view on the line -x; Fig. 3 across-sectional view on the line jL/-Jg Fig. 4, a similar view With theleaves or blades closed; Fig. 5, a view of a modification.

Similar reference numerals in the several figures indicate similarparts.

The front plate 1 of the register is of the ordinary construction,preferably constitut- Ing a support for the other operating parts, andsecured to the under side of said plate at the ends are two iiangedplates or castings 2 and 3 preferably independent, but connected, ifdesired, supporting the various operating parts.

The plate 2 is provided With the downwardly extending flange havingapertures (three in the present instance) for the accommodation of thestuds 4 on the ends at the upper sides of the fans or blades 5, and theplate 3 at the other end is provided with similar apertures arrangedclose to the plate 1 for the studs at The studs on the blades or lfans 5are located at the sides of the ends thereof, instead of at or near themiddles as heretofore, in order that the deep box usually employed inregisters for the support of the fans, may be dispensed with, and

Serial No. 466,678. (No model.)

to simplify andlighten the construction of the device, and it will beseen that when said blades are closed they will slightly overlap eachother, as in Fig. 4, and also the last one will engage the under side ofthe plate 1 and effectually prevent the passage of air into the room.

The plate 3 is attached to the plate 1 by suitable ears 6, through whichpass securing bolts 7 and below the apertures provided for the fanstuds, is provided with a recess in which operates a projecting portion8 of a sliding plate 9. This plate is secured in position bya bolt 10passing through a longitudinally extending slot at the outer side of therecess and on its inner side are pins 12 arranged in pairs on oppositesides of the curved edges 13 of the fans or blades 5,in such positionthat as the plate 9 is moved to one side or the other said blades Willbe opened and closed and when closed will be held tightlyin contactpreventing the passage of air, as in Fig. 4. The said plate 9 is furtherprovided with an upwardly extending operating projection 14 passingabove the face plate 1 and is adapted to be held in any position ofadjustment desired by a bow spring l5 located in the recess in plate 6and engaging at its middle the projection 8 on the plate 9, the frictionbeing sufcient to prevent accidental movement, but not to interfere withthe intentional opening and closing of the register.

The above construction is very simple and cheap, besides furnishing noprojecting parts for the accumulation of dust and dirt as do the presentforms of register, is materially lighter than the present style, as thelong box or bearing necessary for fans hung at the centers of the end isdispensed With.

It will be understood that other means than the pins operating onopposite sides of the curved ends of the blades could be provided, and Ido not desire to be confined to the arrangement above described, as forinstance, the ends of the blades could be provided with a curved slot asin Fig. 5, and single pinsl on the plate 9, but such a constructionwould be more expensive besides having more apertures for the passage ofair when the register is closed, and I do not find it as desirable asthe one shown in the other figures. Though I prefer to curve the flangeson the ends of IOO the blades or fans as shown herein, it willlbeunderstood that they could be straight or inclined, so that practicallythe same movement could be given said blades and a single stud operatingbeneath,could be used, the Weight 0f the blades being suiiicient tocause them to fall open, but I prefer the arrangement shown as it issimple, light and cheap.

p I claim as my invention- 1. In a register, the combination With theface plate and supports thereon, of the fans or blades pivoted at thesides of their ends upon said supports, the slide mounted inrigid guideson one of the supports movable cross-h` 3o or blades pivoted at thesides of their ends upon'said supports and having the inclinedendsandthe actuating slide moving in rigid guides having the pinsarranged on opposite sides of the inclined ends for actuating the bladesand holding them, substantially as described.

4. In a register, the combination with the face plate, the fan supportsthereon, one of l them having the recess, and the sliding plateoperating in the recess, of the fans or blades pivoted to said supportsat the ends near their sides and the projections on the sliding platecooperating with the blades for opening and closing them, substantiallyas described.

5. In a register, the combination with the face plate, thetwotlangedplates secured thereto having `apertures for the journals ofthe fans,one`of said plates havingthe recess in its face, the slidingplate operating therein, and the friction spring, `ot the ifausor bladespivoted in the plates near their-sides and arranged to overlap whenmoved `in onedirection, and connectionsbetween said `blad esand thesliding plate `for causing their operation by the movementofthelatter,'substantially as described.
